This invention relates to improvements in valve mechanisms andparticularly that type of valve associatedwith internal combustionengines and one of the objects of the invention is to provide a devicewhich will reduce fuel consumption and more effectively perform thefunctions required of it. I I

Another object of the present invention is to provide valve mechanismwhich may be operated in conjunction with the operation of the motorvehicle and according to driving conditions may be readily adjusted forfuel saving. v

A further object of the invention is to provide valve means which enablethe engine to operate with fewer moving parts and which lends greaterflexibility todrivit still further object ,of the invention is toprovide improved valve mechanism which will make coasting or freerunning more practical and eliminate the necessity'of declutohing etc.all of which tend to make this type ofdrivinghazardous.

Yet a further objectof the invention is "to provide valve mechanismwhich may be employed for interior cylinder cooling. The

valves being suitably arranged and so synchronized as topermit cylinder'airbreathing intermittent of the powerstrokes, thus modifying oreliminating the present -engine air cooling system and reducing theweight in pounds per horsepower.

As the description of the device proceeds the novelty and generalutility of the invention will become apparent. The invention itselfconsists in-the combination and arrangement of parts hereinafterdescribed in detail" and illustrated in the accompanying drawingsin-which,} y

Figure 9 is an enlarged transverse section taken on theline 9 9lofFigure 5. In referring to the accompanying drawings-in which likecharacters ofereference indicate corresponding parts throughout theseveral views the letter A designates the valve mechanism as a wholerotatably mounted in the internal combustion engine B. The drivingmechanism for the valve being arranged within the housings'G and I Drespectively. y I The valve itselfis of the rotary type and -ismountedin the cylinder head vadjacentto and parallel With the combustionchambers or cylinders 10 and forms a communicating control for thecylinders. Each of the cylinders or combustion chambers are, pro- IVided With an'in let port 11 and an exhaust predetermined periods of theexhaust ports communicate with the, valve, the cylinders and the exhaustmanifold 13. j a Y I F or purposesof mounting and conven ience etc., thevalve .housing which includes the seat 14 is formed with a detachablemember 15 which is secured in position by meansof bolts orthe like 16While the lower portion of the seat is formed inthe'cylinder headproper.

- Referring now to I the valve At which forms an essential feature ofthe lnvention this comprises a hollow longitudinal tubu-- larmember 17;closedat one endand formed with an extended portion 18 in theform ofv enatthie oppositeend as in bustible fuelp I e Arranged in spacedrelationship in the valve body'i provide a series of annular grooves 20which will for purposes of distinction be referred to as exhaustchannels or ports. Adjacent these channels and in spaced relationthereto I provide a further series of exhaust channels or ports 21 whichwill hereinafter be referred to as exhaust compression ports, theselatter ports'it will 7 be noted are arcuate in formation and em- Themeans which I employ brace only a small portion of the periphery of thevalve body. Adjacent the exhaust compression ports and in spacedstaggered relation arethe fuel inlet ports 22. These ports as indicatedin Figure 3 are comparatively wide and communicate directly with theinterior of the hollow valve 17 as shown in Figure 7. Lubricating meansfor the valve comprise an oil cup or the likev 23 mounted in the head 15and which communicates by way of the channel 24 with the reservoir 25formed in the valve A. The reservoir, through a series of passageways26, communicates with an annular reservoir 27 formed within the hollowchamber 17 and which distributes the lubricant to the valve seat andbearing li ing-28 by way of the passageways 29.

For purposes which will be hereinafter more fully related the valve A ismovable axially within the seat 14 so as to, change the relativepositions of the exhaust chan nels and the exhaust compressionchannels.

The means which I provide toenable this axial movement of the valve tobe efiected comprises a coil. spring 8Ov encircling the shaft18. Thespring is held between the thrust bearing 31 which butts the shoulder 32of the valve and the collar or fitting 33, the thrust bearing permittingthe free and easy rotation of the valve when in operation. The meanswhich I have illustrated for rotating the valve A comprises thecomparatively wide gear 34-, mounted on and having meshed therewith thegear 35. The gear and a bevel gear 36 are both mounted on the shaft 37.gear 36 is a further bevel gear 88 which is mounted on the verticalshaft 39. Thisven tical shaft extends into the housing G and at itslower end is provided with a further bevel gear &0 meshing in turn withthe bevel gear ll which is mounted on the crank shaft 42 from whichsource the valve is rotated.

As a means for introducing a combustible fuel through the hollow valveinto the cylinders 10 I provide an inlet passageway 43 which is formedin the cylinder head and which communicates with the openend 19 of thevalve -A. In, the present instance I indicate the fuel control means inthe form of a carburetor 44: which may beattached directly totheintroduction end of the inlet 1-3. The carburetor may be of any wellknown type andis controlled through the operation of a foot accelerator.v to move the cylinders.

the shaft 18" w for starting and running Meshing with the .the vehiclehas been under valve axially may be of any suitable type arranged in anyconvenient manner or operative position, for instance the operatingplunger d5 may be connected to the accelerator or associated with thesteering wheel or on t is other hand it may be mounted on the instrumentboard or connected to the brake pedal, as a matter offact all thesemeans could be employed and each one operated independent of the otheraccording to convenience.

In one of the present illustrations (see Figure 3) I have indicated therod or plunger 15, w iich would be centered on the spider in the openend 19 of the valve, as being operated from the instrumentboard e6 by aknurled nut 47 secured to a threaded rod. The member aawoald. preferablybe formed in an independentsection so that the operation of onemechanismwould not interfere with the other.

In Figure 1 particularly I illustrate the valve control as beingoperated in conjunction with the accelerator d8. which is connectedthrough the bell crank lever ltland pivotal lever 50 with theplunger 45,

In operation and assuming that the engine is dead the channels 20 of.the exhaust would be .1 register with the exhaust ports 12 and the inletports 22would be in register with the intake ports 11. In this. positionno vacuum or compression can take place in the Now assumethat the engineis to be start d, the plunger 45 is operated to move thevalve A axiallyin a forward direction so as to bring the exhaust compression ports 21into register with the exhaust LPOITS 12, at the same time the wide fuelinlet ports 22 remain in register with the fuel inlets 11 and thecomparatively wide gear'3 1sli'des ,to a forward position and remains inmesh with the gear 35. The'engine is now ready under ordinary trafiicconditions.

the operation of l ly-device assume now tiiat operation and has movedout of,cong ested-tratiic and a lcng'hill or othercoastingconditionspresent themselves. The driver of the vehicle immediatelyreleases the member ilewhen "the. pressure of the springSQ will causethe ,valve A to move rearward to-.,its normal original position and thechannels 20 will agam be 1n register with the exhaustiports 12. This,latter operationas previously explained will eliminate vacuum and,compression'and permit the free running ofthe en glue 1 without the.necessity, of de-clutchint: and at the same time effect'the-e'conomicaloperationof the engine with regard to fuel consumption,

In'the foregoing it will benote'd'thatI employ a novel means ofintroducing and regulating the fuelsupply to the combustion For purposesof; further explanation asto. v
